Description of the Invention: [Technical Field of the Invention] The present invention relates to a battery cover for a battery cover which is integrally formed by a blasting portion, and is formed by a press forming process. The cover is made and annealed at the location where the cover is made. The square blasting portion can be used without any need to use the battery used in mobile devices such as mobile phones from the lightweight eve of the (4) | The sealed type battery with j charge and discharge is placed in the outer casing. The sealed battery of the battery can be discharged. The following two wells exist: the second well: excessive exposure, etc., resulting in the inside of the battery: There is a breakdown of the welded portion of the battery case wall, the battery case, and the cover, and there is a possibility of internal liquid leakage, etc. However, when the battery case is used for, for example, a mobile phone, 5 〇 _ visibility 30 _ thickness of about 6 mm Small size, therefore, the plate system for the pool box must rely on the advantages of workability such as drawing processing and thinning stretching (also called W plus two). In addition, it will be used in large mobile machines such as automobiles in the future. Battery It is conceivable to use a method in which the sides are expanded by A 2 to 1 (about) times in accordance with the above-mentioned size, and the materials for the battery case are easily processed by DI, and are required to be lightweight and high. Strength, workability, as a material satisfying this property, for example, Patent Document 1 proposes an A3003 series aluminum alloy plate, the 3UXP/invention specification of the plate (supplemental outer (10) milk (4) defeat 5 200824171 mass% is Μη (Κ8~ The remainder is mainly for the slab; the weight of the plate is Μη from the inevitable 2·〇%, Fe 0·6% or less, Si 〇·3% or less, and further, in Patent Document 2 An aluminum alloy 〇·3~1·5%, Fe 1·6~1·8%, and the remaining part of impurities are proposed. In recent years, as described in Patent Document 3, a type of explosion-proof function is proposed. When a certain internal pressure has occurred before the above-mentioned damage accident, the specific part of the battery cover is destroyed, and the accident is prevented. The explosion-proof part has various specifications, but when the thickness is usually about 2 (), - Generally, the pressure resistance of the explosion-proof part is set at about 3 MPa. Precisely, and the explosion-proof part is made to be damaged by the pressure in the vicinity.

However, there is a good effect that the cost of the inspection is drastically reduced. However, in the invention described in Patent Document 3, since the step of additionally attaching the metal thin plate as the explosion-proof portion is required, the same manufacturing step is increased. Although it is not necessary to inspect the film thickness of the thin metal plate, it is necessary to additionally check whether or not the film is appropriately attached. Therefore, the number of manufacturing steps of the entire battery is increased, and the workability is poor. [Patent Document 1] Japanese Patent Laid-Open Publication No. JP-A No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. 312XP/Invention Manual (Supplement)/96-03/95143892 6 200824171 [Summary of the Invention] (The problem to be solved by the invention), the one that is used to solve the above problem, provides an explosion-proof part = (4) The battery cover test alloy plate is used to prevent the damage caused by the increase of the internal pressure in the battery a while suppressing the damage caused by the increase of the internal pressure in the battery a. It is also unnecessary to perform the inspection of the thickness of the explosion-proof portion after the press forming, and the annealing treatment for adjusting the strength is not required. _ (Means for Solving the Problem) In order to make maximum use of the advantage that the sheet portion is integrally formed on a part of the lid, the inventors of the present invention have attempted to develop a thin alloy sheet which does not require film thickness after forming, and as a result, found that: The ingot alloy plate of a specific composition is used as a tantalum material, and the explosion-proof portion is formed into a sheet shape by press working, and sufficient pressurization strength can be obtained by the press working, and annealing treatment for the purpose of strength adjustment is not required, thereby completing the present invention. 10, the hair-type battery cover (four) alloy plate is characterized in that its composition is expressed by mass%, containing Fe h 15~1.35%, Μη 0.40~0._, and further contains Ti 0.005~〇, 15% or Ti 〇〇〇5~〇15% and β 0.0005~0.05% 'The remainder is composed of A1 and impurities. Si as an impurity is 〇. 15% or less, Cu is 0. 〇5% or less, and % is 〇. 〇5 %the following. - according to the present invention, the battery cover is made of an lg alloy plate, #using the composition of the gold plate, and the battery cover is formed by stamping, the strength of the explosion-proof portion of the press forming is easily obtained to obtain the specified financial strength, and has the required strength Adjusted annealing effect 0 312XP / invention specification (supplement) / 96-03/95143892 7 200824171 . Other than the other battery cover of the present invention, the alloy plate is characterized by being wounded, stamped into a specified thickness, and Explosion-proof part that has not been annealed. 'The battery cover test alloy plate according to the present invention is formed into a portion corresponding to the explosion-proof portion, and is formed into a predetermined thickness, and the stamping is formed into a specified thickness, so that the strength of the explosion-proof portion is relatively easy to obtain the specified resistance even if the annealing treatment is not performed. The compressive strength has the effect of annealing treatment without intensity adjustment. A battery cover ′ having an explosion-proof portion having a thickness of 10 to 3 Å/m, preferably 15 to 27 mm by press working can obtain more excellent effects. (Invention Effect) According to the alloy alloy plate for a battery cover of the present invention, the explosion-proof portion is formed into a predetermined thickness by a waste forming process, and the pressure-resistant strength of the obtained explosion-proof portion conforms to the standard 'and does not need to be adjusted in strength The purpose of the annealing treatment is therefore not caused by the uneven annealing temperature at each position in the annealing furnace during the annealing process, and the strength of the explosion-proof part is uneven. The strength of the explosion-proof part is stable, and the place other than the explosion-proof part will not be inadvertent. The situation of rupture. The appeal is different from the one that sticks to the thin metal sheet. Because the explosion-proof part is integrally formed, there is no danger of liquid leakage due to poor adhesion steps. Therefore, it is possible to provide a sealed battery such as a clock ion battery having a high reliability and a high reliability.

When the content of Fe and Μη does not reach the lower limit value, the specified compressive strength will not be obtained, and when the upper limit is exceeded, the compressive strength will become excessively high, and it is necessary to carry out the purpose of adjusting the residual strength _ In the fire treatment, when the A1—(Fe—Μη)-based compound is coarse and large, the press formability is deteriorated, and it is difficult to obtain an explosion-proof portion having a stable thickness. Ti 0.005~0.15% or Τι 0· 〇〇5~0.15% and B 0.0005~0.05% Τι, or Ti and Β are substances for preventing casting cracks during casting, • Al-Ti or M is formed in the melt. The Ti-β compound has an effect of preventing casting cracks during casting and manufacturing. It is also possible to add only Ti, but when Τι and B are added at the same time, the effect of preventing casting cracks is better. The remainder is A1 and impurities. 312ΧΡ/^0^^0^·(Μί^)/96-〇3/95143892 9 200824171 When Si is more than 0.15%, Cu is more than 0. 05%, and % is more than 〇·〇5%, The press working increases the unevenness of the work hardening, and it is difficult to obtain an explosion-proof portion having a stable compressive strength. Further, Si forms an A1_Fe_Si-based compound and deteriorates press formability. It is difficult to obtain an explosion-proof portion having a stable thickness. Therefore, it is desirably as small as 12% or less, preferably 0.10% or less. The content of the hetero-f in 〇 is within the usual range 'e.g., Zn is 〇. 25% or less', preferably 〇.20% or less. It is considered to be 0.10% or less, preferably 0.05% or less. For example, the surface alloy plate of the composition can be manufactured into a battery cover plate by a usual manufacturing method. That is, the melt of the adjusted composition is subjected to a solution heat treatment in accordance with the need Z after casting, and the alloy plate having the thickness of hot rolling and cold rolling is appropriately increased. The alloy plate can also be a coffin 'for example, the man-made stamping forming' needs to be about 15% or more; 俨::吏::化' can increase the strength of the cover body without being easily affected by the plate. The finer the crystal grain size of the Q material, the higher the pressure resistance value obtained by the good punching formability. The average crystal grain size can be stabilized in the illusion of the illusion ’i.: Below 25 #111, there is no coarse knot, so. The casting method can be either DC method or cc method.

That is, the standard value is reduced by thinning, and if it is up-regulated, it is thick. When the degree of the explosion-proof portion is less than 10 #111, the sheet portion is likely to be broken, which is not preferable. It is best to be 15 or more from m. The upper limit value is also affected by the standard value, and when it is kept below 3 m, the effect of the present invention can be exerted on other alloy sheets. It is best to be below 27 /z m. In this way, only through the stamping forming, the standard value of the explosion-proof portion can be met, and the annealing treatment of the adjustment strength is not required. _ In addition, the thickness of the board should be changed in accordance with the strength of the battery model. Further, the battery cover of the component board of the present invention is excellent in laser welding properties to the battery case. (Examples and Comparative Examples)
